ChronIC RF hacking tool for TI Chronos watch

Adam Laurie (a/k/a/ Major Malfunction) is a white hat hacker from London, UK, who has presented at a number of conferences worldwide. He’s also the Director at Aperature Labs, Ltd. His latest explorations involve the world of RF remote control systems operating in the unlicensed ISM bands. He used the FunCube dongle to monitor the transmissions from various devices operating in the 433 MHz ISM band, along with free open source GNUradio and Audacity for signal acquisition and analysis.

As a result he discovered that many types of transmissions on the 433 MHz band are capable of being spoofed by the TI ez430 Chronos Watch. In order to simplify this use of the Chronos watch, Adam developed and released a software RF hacking package known as Chronos Integrated Commander (ChronIC).

“It’s basically a cut-down RFCat-like firmware package that allows you to use the watch to transmit arbitrary signals. You can set it up either from the watch itself, or via the original Chronos dongle with a Python helper, and then the up/down buttons on the right of the watch do the transmitting.”

The full project log can be on found on Adam’s blog. The ChronIC code can be found on GitHub.
